ACRA is the gatekeeper for every Singapore business
The Accounting and Corporate Regulatory Authority (ACRA) is the Singapore government body responsible for registering and regulating business entities, public accountants, and corporate service providers. No business can legally commence operations in Singapore without first registering with ACRA. That applies whether you are setting up a private limited company, a sole proprietorship, a partnership, or a limited liability partnership (LLP). ACRA maintains the public register of all registered entities through its online portal, BizFile+, which anyone can search to verify a company's existence, directors, shareholders, and filing history. Think of ACRA as the single source of truth for Singapore's corporate landscape.
What ACRA actually regulates and enforces
ACRA's remit goes well beyond registration. It enforces compliance with the Companies Act and related legislation, sets accounting and auditing standards, and oversees the conduct of public accountants and corporate service providers (CSPs) operating in Singapore. If a company fails to file its annual return, appoint a company secretary within the required period, or maintain a registered office address, ACRA has the power to investigate and take action, including striking a company off the register. For founders, this means ACRA is not a one-time hurdle at incorporation; it is an ongoing regulatory relationship that requires active management throughout the life of the company.
BizFile+ is where registration and filings happen
BizFile+ is ACRA's online portal for all corporate transactions. Company incorporations, name reservations, annual return filings, changes to directors or shareholders, and updates to a company's registered address are all handled through BizFile+. The portal is publicly accessible, so counterparties, banks, and investors can look up any registered entity at any time. Banks routinely request an ACRA profile (sometimes called a BizFile extract) as part of their Know Your Customer (KYC) process when a company opens a corporate account. Keeping your BizFile+ records accurate and up to date is therefore not just a compliance requirement; it has direct practical consequences for your business relationships.
Annual returns and ongoing compliance obligations
After incorporation, every Singapore company must file an annual return with ACRA within a prescribed period after its financial year end. The annual return confirms the company's current particulars: directors, shareholders, registered address, and share capital. Separately, companies must hold an Annual General Meeting (AGM) unless they qualify for an exemption, and they must maintain proper accounting records. ACRA also requires companies to appoint a qualified company secretary within six months of incorporation, and the secretary must be a Singapore resident. Failing to meet these deadlines can result in penalties, and persistent non-compliance can lead to the company being struck off the register.
How ACRA's role connects to your broader compliance picture
ACRA handles the corporate registry side of compliance, but running a Singapore company involves other regulators too. The Inland Revenue Authority of Singapore (IRAS) handles corporate tax, and the Central Provident Fund (CPF) Board oversees mandatory employee contributions. ACRA and IRAS work in parallel: your company's financial year end, registered with ACRA, determines your tax filing deadlines with IRAS. Getting your ACRA filings right from the start sets the foundation for everything else, from opening a bank account to hiring staff to filing your first corporate tax return. Many founders work with a corporate services provider to manage these obligations so they can focus on running the business.
ACRA is not a one-time hurdle at incorporation; it is an ongoing regulatory relationship that requires active management throughout the life of the company.
How ACRA registration and ongoing compliance works
Reserve your company name
Before incorporating, you must reserve your proposed company name through BizFile+. ACRA checks the name against existing registrations and a list of restricted or undesirable words. Approved names are reserved for a set period, giving you time to complete the incorporation. If your preferred name is too similar to an existing entity or contains a regulated word (such as 'bank' or 'law'), ACRA will reject it and you will need to propose an alternative.
File the incorporation application
Once your name is approved, you submit the incorporation application through BizFile+. This requires details of the company's directors, shareholders, share capital, registered office address, and company constitution. At least one director must be ordinarily resident in Singapore, meaning they hold Singapore citizenship, permanent residency, or an eligible pass. Overseas founders who do not have a local director can appoint a nominee director to satisfy this requirement. Duellix handles the full incorporation filing, including name reservation and preparation of the company constitution.
Receive your Unique Entity Number (UEN)
On successful incorporation, ACRA issues a Unique Entity Number (UEN), which is the company's permanent identifier used across all government agencies and business transactions. The UEN appears on invoices, tax filings, CPF submissions, and any correspondence with government bodies. You will also receive a business profile (BizFile extract) confirming the company's registered particulars, which banks and counterparties will ask for.
Appoint a company secretary
Every Singapore company must appoint a qualified company secretary within six months of incorporation. The secretary must be a natural person ordinarily resident in Singapore. The company secretary is responsible for ensuring the company meets its ongoing ACRA obligations: filing annual returns, maintaining statutory registers, and keeping the company's BizFile+ records current. Many companies outsource this role to a corporate services provider.
File annual returns and maintain compliance
Each year, the company must file its annual return with ACRA after its financial year end. The annual return updates the public register with the company's current directors, shareholders, and registered address. Companies must also prepare financial statements in accordance with Singapore Financial Reporting Standards (SFRS). Smaller companies may qualify for audit exemption and can file unaudited financial statements instead. Missing the annual return deadline triggers late filing penalties, so most founders set up a reminder system or delegate this to their corporate secretary.
Update ACRA whenever company details change
Any change to the company's directors, shareholders, share capital, or registered address must be notified to ACRA through BizFile+ within the prescribed timeframe. This is not optional: outdated records on BizFile+ can create problems with banks, investors, and counterparties who rely on the public register to verify your company's details. Your company secretary typically handles these updates as part of ongoing corporate secretarial services.
Benefits
Single public register for all entities
ACRA's BizFile+ portal gives anyone instant access to a company's registered particulars, making it the authoritative source that banks, investors, and counterparties rely on to verify your business.
Legal standing from day one
Registration with ACRA gives your company separate legal personality, meaning the company can own assets, enter contracts, and take on liabilities in its own name, distinct from its founders.
Structured compliance calendar
ACRA's annual return and filing requirements create a predictable compliance rhythm, which, when managed properly, keeps the company in good standing and avoids penalties or strike-off risk.
Credibility with banks and partners
A clean, up-to-date ACRA profile is often the first thing a bank or corporate partner checks. Accurate BizFile+ records speed up account opening, KYC processes, and contract negotiations.
ACRA compliance in practice
Overseas founder incorporating remotely
A founder based outside Singapore wants to set up a private limited company without relocating. ACRA requires at least one locally resident director, which the founder does not have. By engaging a corporate services provider for a nominee director and a registered office address, the founder satisfies ACRA's residency and address requirements and can complete the incorporation entirely remotely through BizFile+. The company is incorporated as a Singapore-resident entity from day one, with a valid UEN and a public BizFile+ profile that banks and partners can verify.
SME missing its annual return deadline
A small company's director is focused on operations and loses track of the annual return filing window. ACRA imposes late filing penalties for returns submitted after the deadline, and persistent non-compliance can result in the company being struck off the register. Delegating the annual return to a corporate secretary means the filing is tracked and submitted on time, and the company's BizFile+ profile stays current, which matters when the company applies for a bank loan or tenders for a contract.
Foreign company opening a Singapore office
An overseas company expanding into Singapore must register its local entity with ACRA before it can hire staff, open a corporate bank account, or sign local contracts. The registration process involves filing through BizFile+, appointing a resident director, and establishing a registered office address. Once the UEN is issued, the company can proceed with Employment Pass applications for foreign hires and CPF registration for local employees. Getting the ACRA registration right at the start avoids delays across every downstream step.
Startup preparing for investor due diligence
An investor conducting due diligence on a Singapore startup will pull the company's BizFile+ profile to verify directors, shareholders, share capital, and filing history. Gaps or inaccuracies in the ACRA record, such as a director whose appointment was never formally filed or an outdated registered address, can slow the process or raise red flags. Keeping ACRA records clean and current is straightforward when a corporate secretary manages updates in real time, but catching up on a backlog before a funding round is stressful and time-consuming.
Common questions about ACRA Singapore
What is ACRA in Singapore?
ACRA stands for the Accounting and Corporate Regulatory Authority. It is Singapore's national regulator responsible for the registration and oversight of business entities, public accountants, and corporate service providers. Every business operating in Singapore must register with ACRA before commencing operations.
Do I need to register with ACRA before starting a business in Singapore?
Yes. No business can legally operate in Singapore without first registering with ACRA. This applies to private limited companies, sole proprietorships, partnerships, and limited liability partnerships. Registration is done through BizFile+, ACRA's online portal, and results in the issuance of a Unique Entity Number (UEN).
What happens if a company does not file its annual return with ACRA?

Most companies delegate annual return filing to a corporate secretary to avoid missing deadlines.
Can a foreigner incorporate a company with ACRA without living in Singapore?
Yes, but ACRA requires at least one director who is ordinarily resident in Singapore. A foreign founder who does not meet this requirement can appoint a nominee director to satisfy the residency rule. The incorporation itself can be completed remotely through BizFile+.
